+"""
+Create a global variable called myUniqueList. It should be an empty list to 
+start. 
+
+Next, create a function that allows you to add things to that list.
+Anything that's passed to this function should get added to myUniqueList, 
+unless its value already exists in myUniqueList. If the value doesn't exist 
+already, it should be added and the function should return True. If the value 
+does exist, it should not be added, and the function should return False; 
+Finally, add some code below your function that tests it out. It should 
+add a few different elements, showcasing the different scenarios, and then 
+finally it should print the value of myUniqueList to show that it worked.
+
+Extra credit:
+Add another function that pushes all the rejected inputs into a separate global 
+array called myLeftovers. If someone tries to add a value to myUniqueList but 
+it's rejected (for non-uniqueness), it should get added to myLeftovers instead.
